Purchase advice Original rims / sensitivity of the colour selection

Good day, I would need the help of experienced Leon drivers 😉 My brother buys a new Leon FR model. He enthuses for the new colour Mystery Blue, which seems very mysterious to me 😉 How sensitive is the color. Does someone already drive it and have some experience? I would rather like Pirineo’s grey, which is much more relaxed and not so vulnerable, eye-catching against Swirls, fine dust… Or? The accompanying 17″ rims Dynamic II are also Not the most beautiful ones. Are the 7.5×17 ET51 with 225/45 R17? How heavy is the rim and what load does it have? Alternatively, the X-Perience in 17″, the X-Perience in 18″ and the Black Machined in 18″ would be interesting, how wide with which ET, how heavy and what load do these rims have? And the Cupra 1 Black High Gloss rim is very chic, how wide with which ET, how heavy and what load does it have? Is it also available in matt anthracite instead of the shiny sc hwarz? I would like to thank you very much in advance for the information, wish you a nice day and send my best regards te-75
